Description

Technical Field

[0001] This invention belongs to the field of forklift technology, specifically, it relates to an omnidirectional mobile forklift. Background Technology

[0002] Forklifts are industrial material handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. Unlike large and medium-sized enterprises, most small and medium-sized enterprises and township enterprises have relatively small workshop environments, cluttered items, and poor 6S on-site management. When traditional forklifts are used for inserting goods, the forklift body moves synchronously with the forks. In confined spaces, the forklift body cannot enter, thus limiting the forklift's usability. At the same time, forklifts cannot turn in narrow aisles, resulting in low efficiency in forklifting and moving goods.

[0003] In view of this, the present invention is proposed. Summary of the Invention

A guide connecting plate 26 is fixedly installed at the lower end of the connecting columns 25. A steering wheel rotation power box 29 is fixedly installed on the bottom surface of the lifting plate 28. A rotation output shaft 37 is installed below the steering wheel rotation power box 29. The lower end of the rotation output shaft 37 is fixedly connected to a rotating mounting base 31.

[0032] See attached. Figure 9 The lifting plate 28 is symmetrically provided with guide ears 34 on both sides. A guide rod 27 is fixedly provided on the upper surface of the guide ears 34. A guide connecting plate 26 is provided with a guide mating hole that matches the guide rod 27. The stability of the lifting plate 28 during the lifting adjustment process is ensured by the cooperation between the guide rod 27 and the guide mating hole.

[0033] See attached Figure 7A rotary power motor 30 is fixedly installed below the steering wheel rotary power box 29 on the side of the rotary output shaft 37. The main shaft of the rotary power motor 30 is connected to the active output shaft 38 through a coupling. A drive gear 36 is installed on the active output shaft 38 through a key. A driven gear 35 is meshed on the side of the drive gear 36. The center of the driven gear 35 is connected to the rotary output shaft 37 through a key.

[0034] The output shaft 37 is concentric with the hydraulic rod 24. The rotating mounting base 31 has an inverted U-shaped structure. The side of the rotating mounting base 31 is fixedly mounted with a travel motor 33. The main shaft of the travel motor 33 is connected to the rotating shaft of the load-bearing steering wheel 32. The travel motor 33 provides power for the travel and rotation of the load-bearing steering wheel 32.

[0035] The upper surface of the telescopic fork arm 8 is flush with the upper surface of the main fork arm 6. The fork arm fixing connection plate 5 is perpendicular to the main fork arm 6. The front end of the telescopic fork arm 8 is provided with a fork guide ramp to facilitate the insertion of goods.

[0036] See attached Figure 6 The side pedal 9 is fixedly connected to the forklift body 1 via a hinge 22. A support limiting plate 21 is fixedly installed at the middle position of the outer side of the side pedal 9. When the side pedal 9 is flipped to the horizontal state, the end of the support limiting plate 21 contacts the forklift body 1 to ensure the structural support stability of the side pedal 9 in the unfolded state.

[0037] See attached Figure 1 A seat 11 is installed on top of the forklift body 1. The seat 11 is equipped with a seat belt. A steering wheel 12 is installed in front of the seat 11. A control box 13 is installed on the side of the steering wheel 12. A gear shift lever is installed on the side of the control box 13. The control box 13 is electrically connected to the electric telescopic rod 18. A protective canopy frame 10 is installed on the forklift body 1 above the seat 11 for safety protection.

[0038] There are four connecting columns 25. A guide connecting plate 26 is installed between two connecting columns 25 near the guide rod 27 on one side. There are two lifting device mounting slots 14. Each lifting device mounting slot 14 is equipped with two sets of steering wheel lifting devices 15. The steering wheel lifting devices 15 are fixed by bolts for easy disassembly and assembly.

[0039] There are two main fork arms 6 symmetrically arranged about the forklift body 1. The electric telescopic rods 18 inside the two main fork arms 6 are connected in series. The two electric telescopic rods 18 extend and retract synchronously, thereby driving the telescopic fork arms 8 to extend and retract synchronously.

[0040] The working principle of this invention is:

[0041] Example 1: When using this forklift device to pick up and place goods, if the goods are placed on the side of the safety passage, the goods can be picked up directly. At this time, the section of the telescopic fork arm 8 with the guide slope is located on the outside of the main fork arm 6, and the remaining section is retracted in the fork arm mating groove 7. The length of the extended fork arm is relatively small, which can meet the needs of conventional forklift transportation of goods.

[0042] Example 2: When it is necessary to pick up or put down goods far from the safety passage, and the forward movement of the forklift body 1 is obstructed or restricted due to the relatively narrow passage, the electric telescopic rod 18 installed in the cavity of the main fork arm 6 can be activated by the button on the control box 13. The two electric telescopic rods 18 in the two main fork arms 6 are connected in series in the circuit and can be extended and retracted synchronously. The electric telescopic rod 18 extends and drives the telescopic fork arm 8 to move outward along the fork arm mating groove 7, so that the overall length of the fork arm increases, which facilitates the forklift operation. After the goods are picked up onto the telescopic fork arm 8, the electric telescopic rod 18 retracts, and drives the goods to move horizontally onto the main fork arm 6. Since the upper surface of the telescopic fork arm 8 is flush with the upper surface of the main fork arm 6, the horizontal movement can be achieved. Then the forklift can be driven out to complete the picking up of goods in the narrow and obstructed passage.

[0043] When the passageway is narrow, it is often inconvenient to operate the forklift body 1 when retracting after picking up goods. The forklift cannot turn and is prone to hitting other shelves during reversing, which requires a high level of skill from the forklift driver and also poses certain safety hazards. At this time, the lifting plate 28 can be moved downward by the hydraulic rod 24, so that the load-bearing steering wheel 32 contacts the ground and the traveling wheels of the forklift body 1 leave the ground. The load-bearing steering wheel 32 is equipped with a traveling motor 33 and a rotary power motor 30. The main shaft of the rotary power motor 30 drives the active output shaft 38 to rotate, and the active output shaft 38 drives the active gear 36 to rotate. Since the active gear 36 and the driven gear 35 mesh with each other, the driven gear 35 is driven to rotate. The driven gear 35 drives the rotary output shaft 37 to rotate, and the rotary output shaft 37 drives the rotary mounting base 31 to rotate, which in turn drives the load-bearing steering wheel 32 to rotate. After the load-bearing steering wheel is adjusted to a certain direction, the forklift body 1 can be turned and moved in place under the action of the traveling motor 33, which effectively improves the transportation safety of the forklift when picking up and placing goods in narrow passages.

[0044] The steering wheel lifting device 15 is fixedly installed in the lifting device mounting groove 14 on the bottom surface of the forklift body 1 by bolts, which facilitates overall assembly and disassembly. The steering wheel lifting device 15 is an optional structure that can be selected and installed according to the specific conditions of the factory warehouse. When not installed, it is a traditional normal walking transport forklift. When installed, the walking direction can be adjusted on the spot, making it more versatile.

[0045] The forklift of this invention features a telescopic fork arm design, consisting of a main fork arm 6 and a telescopic fork arm 8. An electric telescopic rod 18 is installed inside the cavity of the main fork arm 6. The electric telescopic rod 18 can drive the telescopic fork arm 8 to extend and retract within the fork arm mating groove 7. In confined spaces where the forklift body 1 cannot access, the fork arm structure can be extended to enter narrow passages for retrieving goods, effectively expanding the forklift's usability. Simultaneously, a lifting device mounting groove 14 is provided on the bottom surface of the forklift, within which a steering wheel lifting device 15 is installed, allowing the fork arm to... The vehicle can turn on the spot, making it easy to move and exit in narrow spaces. The steering wheel lifting device 15 can be adjusted for height by the action of the hydraulic rod 24. Guide rods 27 are provided on both sides of the lifting plate 28. The guide rods 27 cooperate with the guide connecting plate 26 to ensure the stability of the lifting plate 28 during the lifting and moving process. The load-bearing steering wheel 32 is equipped with a rotary power motor 30 and a travel motor 33, which can realize the travel and rotation of the load-bearing steering wheel 32. The side of the forklift body 1 is equipped with a folding and storage structure side pedal 9, which is convenient to step on during the loading and unloading process.
